Changelog

Notable changes to deckwright, newest first. The project is pre-1.0 — pin to a tagged release; main is the development line.

v0.6.0 — 2026-10-04

On pf-core 0.25.

Components

code measures its lines in the theme's mono face, inside the plate's padding and rounded corners. A listing with a line wider than its plate is refused unless it sets wrap: true, and a wrapped listing's plate is as deep as the rows its lines wrap to.
code draws a tab as spaces to the next multiple of four columns, does not charge a line's trailing spaces, and charges a space its face may lack a full em.
code sets its rows exactly 1.55 times the type size apart, the advance its plate is sized for, and moves the leading above its first row from the plate's top margin to its bottom one.
Courier New, Liberation Mono and Cousine have a width table of their own, covering accents, Greek, Cyrillic, arrows and box drawing. A mono face without it is charged the widest monospace advance measured for Latin, and the widest glyph of its class beyond it.
code refuses a placement too narrow for its plate's padding to leave room for a line.

Type

Fit estimates break a line where LibreOffice does: never beside a no-break, figure or narrow no-break space unless a hyphen or en dash comes before it, nor after a hyphen before a digit, between two hyphens, or after a hyphen opening a word. An overlong word in text carrying CJK keeps its kinsoku.

Render and QA

overflow reports a line set on a plate — a code listing — that the render does not hold inside that plate.

v0.5.0 — 2026-09-30

On pf-core 0.24.

Spec

An unquoted yes, no, on or off in copy — a table cell, bullet, chart category or title — prints as written. Fields that take true or false read those words by the truth they spell. banding, wrap, a cell's emphasis and a versus side's highlight refuse a value that is not a boolean, where a quoted 'no' turned them on.
Optional copy written no or off — a bullets heading, a stat label or caption, a callout or flow body, a versus note, an image's over text — is set instead of dropped.
A key YAML reads as a date, a boolean or a number, written beside a misspelt key, is refused with the unknown-key message, naming the key as YAML read it, in a spec and a theme alike.

Theme and conform

A theme with a non-finite chart number; a NUL, over-long name or symlink loop in template: or icons:; nan% or inf% in scale:; a type size at or below zero, line_weight_pt: 0 included; a reference_height too small to divide by; or a face that is not one name is a ThemeError naming the key and its value.
conform skips an accent that stands off the page it derived by neither 3:1 contrast nor 35 ΔE, as it skips unedited stock accents, and its report names each accent skipped. Re-adopting a template whose accent matches its page changes that theme's accents.
conform loads its theme and flattens a template's master picture once per run instead of once per exercise.
conform reports each pair of accents it binds that sit closer than 35 ΔE.
A theme that binds its own page and no line gets a line derived from that page. On a dark or coloured page, rules, table rules and edges drawn in the default line change colour: a rule is drawn in muted, as it is on a light page.

Components

equation: sets one display equation from a LaTeX subset, written as PowerPoint stores an equation: Office Math in an mc:AlternateContent Choice, and a Fallback of one line of UnicodeMath, which readers without Office Math and every check read.
A document: card's corners and shadow blend on a dark or coloured slide, where they sat on a white matte.
A document: card shows the pictures its markdown names from the markdown's own folder: ![alt](path), an <img> or srcset, an SVG <image>, a <video> poster, or a CSS url(). One named from anywhere else is refused.
A document: card draws a markdown table as ruled, padded cells.
A bullets list is measured item by item as its items wrap, with the space after each item, and a list whose tallest column would run past its placement is refused, naming the bullets and the lines they wrap to.
swatches reads columns:: 1 to 8 chips per row, clamped to the number of roles. Any other value is refused. A row after the first starts below the labels of the row above.
diverge paints each direction in the first accent, then the label ink, that stands off the ground behind its bars.

Charts

highlight: true shows on a pie or doughnut: the marked wedge keeps the first accent and the rest fade that same accent toward the chart's ground, at two alternating depths, each still standing off the ground itself. On a chart with several series the marked row keeps each series' colour and the other rows fade. A highlight needs no second accent.
No two touching pie or doughnut wedges share a colour, the last and first included. Where the accents run short, a wedge takes a tint or shade of an accent.
A ChartSpec built in code with a highlight its kind cannot show is refused.
A pie's data labels are pinned to ctr, so a small wedge's label no longer lands outside the pie in the ink chosen for the wedge it named.

Motion

A click-to-reveal trigger is written in PowerPoint's own form: its sequence advances on a click of the trigger alone, not on the slide's next click.
A slide takes transition: morph, written as PowerPoint's Morph transition with a fade as its fallback, and a placement takes morph: <name>, which names its shapes alike on each slide that carries the name, for Morph to pair.

Render and QA

render rasterises each page to a whole number of pixels, so a dark slide no longer shows a light line down its right edge.
qa reports series-colour when two series in one chart share a fill.
qa reports morph-unpaired: a morph: name with no namesake on the slide before, or a morph slide that names nothing.
qa reports link-contrast: the template's link colour, which Keynote draws, against each linked shape's ground.
render links each typeface the deck names that fontconfig has installed under that name into LibreOffice's profile, so those faces, and CJK text, render in their own type.
render writes a stamp beside its output, and qa reuses a render whose stamp matches the deck on disk instead of converting the deck again.
qa's text-fit measures bullets columns and counts paragraph spacing; the manifest records space_after_pt.
qa's shape-id and shape-name count ids per mc:AlternateContent branch. extract reads a wrapped shape from its Fallback, and a build's paragraph builds judge a wrapped shape by its Choice.
qa's package checks resolve a relationship target that names its part from the package root.

Reading decks

diff reads a copy saved under another name against its build, when the copy sits beside the manifest: a built deck carries its build id.
diff no longer reports a table's cells or a chart's parts gone from an untouched deck, and reports a slide deleted, pasted in, duplicated or moved as one line.
diff reports a shape restyled or relabelled, and a slide retimed: its build's clicks, revealed shapes or triggers changed, or its transition did.
The manifest records the transition each slide arrives on.
The manifest records both lines of a swatches label, the role and its hex, so diff no longer reports every chip retyped.
extract drafts a deck deckwright built as the placements that built it — card, bullets, prose, table, chart, image, rule and panel — each at the box its manifest recorded, with its id:, morph:, reveals: and a plate's pair:, and the slide's animate: and transition: morph. Another component comes back as bullets of its words, or as an image when it holds only a picture, and the draft says so; so does a reveal a spec cannot state, which is left out.
extract drafts a chart from any deck as a chart: block with its kind and data, and a filled shape holding a heading and a line, or a text box lying on one, as a card:.
extract drafts a picture as an image: with its alt text or decorative flag, a photo in a picture placeholder included, and writes its file to a <draft>.media folder beside the draft. An existing folder is refused without --force, and replaced with it. A picture that would push a slide's words off it is named instead.
A slide holding more than the grid bands names each table row, chart and picture left over; a slide read back by placement names what was added to it by hand.
extract --as md lists each picture's alt text, a card's words, and a chart's data.

Development

bin/test runs the suite in parallel when pytest-xdist is installed; bin/test -n0 runs it serially.
lxml and rich are declared dependencies, and pytest-xdist is a dev dependency.

v0.4.0 — 2026-09-14

Accessibility

image, icon, document and chart take alt:, written as the shape's alternative text, and decorative: true, written as Office's decorative flag. Giving both is refused.
A slide's background image or theme art, and a card's picture icon beside its words, are marked decorative. card takes alt: and decorative: for its icon.
Pictures no longer carry their file name as alternative text.
qa reports alt-text: a picture or chart with neither alt text nor the decorative flag, or with only a file name. WARN.
The manifest records alt and decorative per shape.
extract writes each dropped figure's alt text into the draft as a comment.

CJK

Chinese, Japanese and Korean text is measured at one em per ideograph, kana, hangul syllable and fullwidth form, instead of the widest Latin glyph, and wraps where the renderer breaks it: between ideographs and kana, at spaces in Korean, with kinsoku (closing punctuation and small kana never start a line, opening brackets never end one) and a trailing full stop or comma hanging past a full line.
Each run carrying CJK is written with its lang and the theme's face for its script. The theme takes those faces from type.ea (ja, ko, zh-Hans, zh-Hant), else from the template's fontScheme script entries.
The deck and each slide take lang:. Han-only text with no lang: is refused on a theme that sets Japanese and Chinese in different faces, which most brand templates do.
qa's font-substituted reads the fonts the rendered PDF embeds (Poppler pdffonts), falling back to fc-list. A face installed but unreachable by LibreOffice is now reported.
qa reports cjk-unrendered: a slide with CJK text whose render embeds no CJK font. ERROR.

Reading decks

inspect and diff read a shape stored inside mc:AlternateContent from its fallback. inspect listed nothing for one, and diff reported it gone.

v0.3.0 — 2026-09-12

Licensed Apache-2.0, replacing MIT, with a NOTICE file. The distribution's license metadata is Apache-2.0.
python-pptx is pinned to ~=1.0.2.

Theme and conform

conform derives inverse against the page a slide shows. A dark master gets a light inverse and its own inverse-ink; a light-page template derives as before. Re-adopting a dark-page template changes its inverse surfaces.
Loading a theme whose inverse is within 3:1 of its page logs theme_inverse_matches_page. Re-adopting its template rebinds inverse and inverse-ink, bound or left at the default; conform without --adopt reports it.
Re-adopting a theme keeps its comments and layout: only the lines whose values change are rewritten. A change a line edit cannot make, such as a flow-style bind:, rewrites the file and logs theme_comments_dropped when it had comments.
conform's report names the page, ink and inverse of the theme it wrote, each with its contrast, instead of the colour scheme's pair; an unbound one is marked (default).
A template outside the theme directory whose filename is already taken there is refused without printing an mv over it, by conform --adopt and by a theme: naming it.
A template symlinked into the theme directory is adopted where the link is.

Spec

A number in a spec prints as it was written: 1.10 and 2.50 stay as typed in a table or a stat. What YAML 1.1 reads in another base — 007, 0x1F, 1:30 — loads as the text written, and an unquoted crop: 16:9 is that aspect. A whole-number field such as a column index refuses one by name.

Colour

Text a component sets on the slide is inked for what is painted under it: prose, bullets, callouts, captions, nav, fanout, diverge, code, grid and a chart's labels, axis text and legend over a panel or a picture, and a table's body cells on an inverse band. The manifest records that ground, and a picture's scrim is part of it.
A bleed: card, disc, callout dot, versus or fanout plate, diverge plate or bar, or grid bar is the ground for text laid over it, as a panel is. A disc covers its inscribed square.
Text over a picture laid on top of a panel is inked for the picture.

Type

Width tables for Poppins, Open Sans, Montserrat, Amatic, Sniglet, Bebas Neue and Barlow Semi Condensed. Decks in those faces lay out against their real widths, so prose, cards, tables and titles take less room than the conservative estimate gave them.
A fit refusal whose estimate ran on a face with no width table says so.
A card heading or body, a stats value or label, or a flow step holding a run wider than its frame is refused, naming the run and the width it needs, measured without the sizing margin. A run ends at a space, after a hyphen or dash, and at each CJK character. A word that fits its line is no longer counted as two lines by the wrap estimate that sizes cards, flow steps, discs, chrome lines, prose, table rows, picture text and swatch captions, and that qa's text-fit check measures against.

Components

nav with no items: takes the deck's sections:, and with no active: marks the slide's own section: when it is one of the items.
SlideCtx.text_ink and SlideCtx.accent_at return an ink for a box and the ground painted under it, for components written outside the package; ctx.painted takes a Disc for a round fill.

Motion

animate: one_at_a_time reveals a single-column bullets list one bullet per click, as a PowerPoint build by paragraph in one text box. A list with several columns still reveals a column per click, and together is unchanged.
Every component reports a motion role for each shape it reveals, so motion.roles binds how text, surfaces, lines, figures and charts enter; a chart's own build takes the datum entrance. The lines in a fanout and between flow steps now wipe by default, as rule and connector do; a vertical stroke wipes along its length.

Charts

Area, doughnut and bubble charts print their data labels.
An area chart's first and last data labels are moved in off the plot edge, so they do not sit on the value axis.
xy-scatter-smooth and xy-scatter-smooth-no-markers draw curves.
A data label drawn on a series' fill (pie and doughnut wedges, area bands, stacked bars, inside_end bars) is inked for that fill, per wedge where wedges differ.
A chart with one named series is not titled with that series' name.
A chart's data labels, axis text and legend are recorded in the manifest with the ink and ground they are drawn on, so qa's contrast and min-font checks cover them.
A bar or column chart's value axis starts at zero when every value is zero or more. y_min still overrides it; line, area, radar, scatter and bubble keep automatic scaling.

QA

qa warns fill-ground when a shape filled to stand off its ground (an inverse or accent panel, card or disc, a plate, a bar, a dot) is separated from it by neither luminance nor colour.

Errors

Slides whose chapters run out of the order sections: lists are refused, naming both.
A theme: naming a .pptx, at a path or by bare filename, is refused with the theme already adopted from it, or else the conform --adopt command that onboards it, paths quoted and the move into the theme directory included. A theme file that is not UTF-8 text is a ThemeError.
Commands printed by sample and by conform --adopt's refusal quote their paths.
An exception from a component's own code keeps its traceback and ends with a line naming the slide and component. A component's LayoutError is unchanged.

v0.2.0 — 2026-09-04

The project is deckwright. The package, the deckwright command, the DECKWRIGHT_* variables and the .deckwright-cache directory follow the name. A .env carrying PPTXKIT_* needs its prefix changed; a .pptxkit-cache left behind can be deleted. Decks and manifests already built are unaffected — a .pptx never carried the package name.
On pf-core 0.22.

Extract

deckwright extract <deck>.pptx drafts a .deck.yaml from a deck deckwright did not build. Kickers, titles, subtitles, body text, tables and speaker notes convert; every shape it cannot turn into words is named in a # not converted: comment on the slide it came from, repeats collapsed into N × kind. --as md writes a plain transcript instead, --out chooses where it lands, and --theme is loaded, so the draft's rows: spans that theme's grid and an unknown name fails before anything is written. out: defaults to out/<slug>/<title> v1.pptx, the same slug deckwright new uses.
extract walks grouped shapes, reads chrome back out of the shape names build writes, so a deck deckwright built keeps its kicker, title and subtitle, and takes a slide's first block as its title when it is one line set larger than everything else on the slide. Shapes overlapping vertically are one row, read left to right. An element python-pptx cannot build — p:contentPart, mc:AlternateContent — is named by its tag.
extract recovers a slide's background: when the colour painting the whole canvas is one the named theme declares. A colour it does not declare is written into the draft as a comment naming the hex.
The bullet marker build writes is taken off again on the way in, so a deck survives any number of extract-and-rebuild round trips. The draft is not otherwise a fixed point — a columned list comes back as one placement per column — but its words are. A leading dot in a deck deckwright did not build is left as content.
build refuses an --out (or an out:) that is the spec being compiled, or that names any .yaml/.yml path — a deck written over its spec leaves nothing to rebuild it from. Rebuilding over an existing .pptx is unchanged. The spec snapshot under .build/ is now taken before the deck is written rather than after.
extract refuses a destination that already holds a file, so the second run over a deck does not replace the draft you edited after the first; --force overwrites. That refusal and an --as that is neither yaml nor md are both raised before the deck is read.
An extracted draft builds as written. A table placement gets the rows its own height will demand at build; every other placement gets a fixed two. A slide holding more than the grid can band runs its blocks together and columns a long list; whatever still does not fit is written in as comment lines.

Motion

qa reads a deck's timing: beats reports each animated slide's rhythm, beat-size warns when one beat of a staged build reveals more than DECKWRIGHT_MAX_BEAT_SHAPES (default 6), and dead-trigger reports an interactive reveal that cannot fire or that reveals what is already on screen. animate: together, a chart build and a reveals: trigger are exempt from beat-size: one click is what each of them declares.
Every build writes <deck>.beats.md beside <deck>.content.md — the reveal order in words, click by click, each section headed by its slide's title.
The manifest records the clicks an animation spends, which is not the number of beats its components grouped: animate: together and an after_previous chain spend one, a chart build spends one per part plus one for its axes, and an interactive reveals: spends none and names its trigger.
A ring of reveals: is refused at build. Chains still build — click one to reveal the next is real staging.

Charts

A pie or doughnut carrying more than one series is refused by name. python-pptx keeps only the first, so the second reached a strict zip and came out as a bare traceback.
A radar series carries no c:smooth. python-pptx writes one for every connected kind and CT_RadarSer has no such child, so the chart part did not validate.
A chart's labels: names the series that print their data labels, so a flat reference series stops stamping the same number over every point.
A chart's value axis takes the same number format its data labels do, so a line whose points read 11.2% sits against a scale reading 0.0%.
Chart data labels keep their decimal places, read off the data — 11.2, 9.6, 5.1, 4.8 labels to one place, whole numbers to none. decimals: overrides it, 0 included, and the *-stacked-100 kinds are no exception: their axis shows the computed share while each label prints its own series value.
qa warns as chart-datapoints when a bar or column chart plots fewer than four values, quoting choosing.md's rule. A warning, not a refusal.
A chart legend goes under the plot on every kind but the bar family, which keeps the column it reserves beside its category labels. The bar family's legend gets a measured column out of the same budget as those labels, and the plot keeps at least 45% of the frame.
A data label takes a position only where the chart group offers one: inside_end is written for the bar family and a pie, the line and scatter kinds sit above their point, and area, doughnut and radar are left without one. A theme naming a label_position does not get to write it into a group that has none.
versus sizes each plate in proportion to its value, so a side 60% larger is 60% wider. Values with no number keep the even split, and so do two written in different units — 2 days against 4 hours reads 2 against 4 and would draw the longer span smaller. A magnitude suffix is part of the unit: $1.2M and $480K do not compare, and neither does a singular against its own plural: the unit is matched whole, because no string rule separates hrs/hr from ms/m. The smaller plate never drops below the width its longest word needs, so a lopsided pair widens rather than breaking type mid-word; a placement too narrow for both sides is refused.
The chart block's annotate: key is gone; a deck still carrying one is refused by name. For a callout on one point, place a callouts or prose beside the chart.

Type and colour

A typo in a theme's scale:, scale.margin: or type: block is refused by name. Only the top level was checked, so a misspelled key was dropped and the built-in default stood — the theme read as though it had been honoured.
The packaged base theme sets larger type. At its 7.5in reference height: body 14 → 16pt, caption 12 → 14, subtitle 16 → 18, lead 18 → 20, head 19 → 22, stat 32 → 34. kicker, title, display and hero are unchanged. A deck on theme: base reflows on its next build: copy that only just fitted may overflow, and a placement whose contents no longer fit their band fails the build rather than shipping short.
A theme with no template: sets colours: bind: accepts a literal RRGGBB for any role, so a palette is a theme of five lines. A slot name in such a theme is refused, naming the two ways out; marks: still needs a template.
A bind: to a literal accent is kept even where it equals a colour Microsoft ships. The stock-accent guard applies to template slots only.
A type-ramp rung reaches the theme's monospace face with face: mono, alongside face: body and face: heading. A face: matching an alias only in case is a literal typeface and warns.
The caption rung takes a half step of the modular scale — 14.3pt at the default reference height, up from 12.8pt — so it no longer shares a step with the bold, capitalised kicker.

Layout

swatches reserves the depth its caption actually wraps to rather than a flat two label lines, so a placement that would have held it is no longer refused.
A placement's anchor: applies to the shapes that placement drew and to nothing else, so editing one slide cannot move another.
A mark's contrast plate stays inside the placement that asked for it.
A chrome box may declare h: auto and take the depth its text wraps to.
prune matches layouts by part name, so it cannot drop a layout a slide is still on.
A section: that resumes after another chapter has begun is refused, naming both slides. A slide carrying no section: of its own does not break the run it falls in.

QA and doctor

deckwright qa adds placeholder: recorded text and speaker notes that read like copy nobody meant to ship — four phrases deckwright new seeds, plus lorem, ipsum, TODO, FIXME, [insert and a run of three or more x in either case. WARN.
deckwright qa adds font-substituted: one finding per theme face the rendering machine cannot set. It runs only when qa renders, and is silent when fontconfig cannot be asked. WARN.
A line the rendered page does not hold is asked for again inside the shape's own box before overflow reports it. pdftotext merges side-by-side placements row by row, so two prose in adjacent columns spliced each other's wrapped lines and the slide was reported twice over.
qa falls back to the theme name a manifest records when the theme_path it records is not there, so a deck handed over on its own is checked against the packaged base rather than refused. A name resolves against the reader's own theme directory first, so theme-substituted reports a file that answered to the name but hashes differently from the one the deck was built against.
deckwright doctor reports whether this machine has the faces the base theme sets type in; without fontconfig, or when base did not load, that row is a SKIP.
deckwright doctor loads the base theme it resolved. One that resolves but will not parse is a WARN naming the file and the loader's message.

Theme and conform

deckwright conform resolves the +mj-lt and +mn-lt font references a template may carry against its own font scheme. load_theme warns when a theme on disk already holds one and names the template to re-adopt.
Counts and margins in scale:, point sizes in type:, millisecond timings in motion:, and every block that must be a mapping are checked at load; a value that will not convert raises ThemeError naming the key and the value. deckwright doctor prints its full table even when a check raises.

Rendering and the CLI

render resolves the deck path as well as --outdir, so a relative input works from any directory, and a relative --outdir lands where the render created it. An input that is not there is reported as itself.
A conversion that writes no PDF is reported instead of rasterising the previous run's, and the failure names the leftover process.
render leaves no render/share directory behind: LibreOffice starts in the throwaway profile it already owns.
deckwright glyphs find <substring> searches the 4,001 glyph names and the alias tables. Hyphens and underscores match either way; --limit caps the output and a capped run says how many it dropped.
Build errors from inside a composite name the component the author wrote — a flow reported component 'card' — and the chrome-box error names its slide.
fc-list (fontconfig) is a new optional external tool; the doctor fonts row and the font-substituted check are silent without it. DECKWRIGHT_FC_LIST and DECKWRIGHT_FC_LIST_TIMEOUT_S point at another binary and cap the call.
Every external tool deckwright reads — pdftotext, fc-list, LibreOffice, pdftoppm — is decoded as UTF-8 rather than the platform locale, and the CLI's own output degrades instead of raising on a console that cannot encode a deck's em dashes.

Documentation

treatments.md says the claim should land a beat before the evidence, and applies the run test to animate:. choosing.md gives the recipe for staging a table's total row into its own beat.
motion.md marks motion.advance as a theme key beside the slide-level animate: and reveals:; placement.md states that anchor moves what a placement drew inside its rect, with the measured positions; components.md gives the icon sizing arithmetic; qa.md says #N counts shapes as drawn, so a contrast plate takes #1.

v0.1.0 — 2026-08-29

Initial public release.

Python 3.12+, on pf-core 0.21.
deckwright build compiles a declarative .deck.yaml against a theme into a branded .pptx, a build manifest, and a .content.md of the deck's words.
Twenty-two slide components, 29 native chart kinds, imagery with fit/crop and scrim solving, HTML panels rendered through headless Chrome, and animation — builds, click-to-reveal and slide transitions.
The built-in base theme ships inside the package, so theme: base resolves with no checkout. A file of the same name in DECKWRIGHT_THEME_DIR takes precedence.
Default faces are Helvetica and Courier New, which resolve to metric clones in Keynote, PowerPoint and LibreOffice alike.
deckwright conform <template>.pptx --adopt <name> derives a theme from a brand template and drives every capability through it.
deckwright sample writes a small brand template to conform against, so the walkthrough needs no brand file. It lands in the theme directory, where --adopt can read it.
deckwright qa checks geometry bounds, reserved regions, WCAG contrast, minimum font size and render-based overflow against a built deck's manifest.
render and qa write into render/<deck>/ beside the deck, so two decks in one directory never overwrite each other's slides.
A built deck carries only the slide layouts it uses; build --keep-layouts retains the rest, and the media only they reach.
Speaker notes declare their notes master on the presentation, which Keynote requires to open the file.
deckwright doctor reports the version, the glyph bundle, theme resolution and the external tools, naming the install command for anything missing. --version prints it on its own.
An absent external tool names the binary, the DECKWRIGHT_* variable that overrides it and the install command for the platform; qa also names --no-render, which runs every check that needs no tool.
~4,000 Material Symbols ship as one archive; deckwright glyphs verify checks it against its manifest and deckwright glyphs sync re-vendors it from upstream — the one command that uses the network.
Supporting commands: render, shot, inspect, diff, new, demo.
One directory for a brand: templates/ holds the .pptx and the theme derived from it, side by side. theme: <name> resolves <name>.theme.yaml there, and a theme names its template by bare filename — nothing is ever copied. A template is adopted where it lives; adopting one from elsewhere is refused.
Re-running conform --adopt on the same template is a refresh that keeps hand edits; --force re-derives and discards them.
The suite's primary guard drives every template in that directory (tests/test_templates.py, DECKWRIGHT_TEMPLATES_MIN to require a minimum).
Headless Chrome runs sandboxed. DECKWRIGHT_CHROME_NO_SANDBOX=1 passes --no-sandbox, which is implied when running as root.
Every rendered card carries a content policy: no frames, objects or embeds, no script but deckwright's own height probe, and images and fonts from data:/http(s): only. A file:// URL in card markdown no longer renders a local file into the deck.
Importing deckwright no longer touches the root logger; handlers land on the deckwright logger, and an application that configured logging first keeps its own.
All text is read and written as UTF-8 regardless of the platform locale.
Every XML part of a .pptx is parsed with entity expansion and network access refused, so a package from someone else cannot amplify or forge through a DTD.
The sdist ships a runnable suite: tests/, docs/ and examples/ travel with it, and brand templates and derived brand themes are excluded from both dists.
